摘　　要：为提供工程设计和放大所需的物性数据和热力学数据，在常压下分别采用U形震动管密度计和乌氏黏度计测定了苯乙烯正辛烷混合液在293．15～363．15K的密度黏度，计算了超额体积V^E以及不同温度组成下的混合黏度的变化，对不同温度下超额体积和黏度变化与组成的关系分别用Redlich-Kister方程进行关联，混合黏度用Andrade公式进行关联．In order to get the data of substance character and thermodynamics used in engineering design and scale-up,densities and viscosities of the binary mixture of styrene with n-octane were determined between (293.15) K and 363.15 K under atmospheric pressure by using a vibrating U-shaped sample tube densimeter and Ubbelohde suspended-level viscometer.Density values were used in the determination of excess molar volume.Viscosities were used to calculate the deviations of viscosity.Excess volume and deviation of viscosity were fitted by the Redlich-Kister equation.Viscosities were done by the Andrade equation.
